NAB calls on US AM/FM stations to cease Russian programming

Many thanks to SWLing Post contributor, Zack Schindler, who shares the following stories all focused on US broadcasters receiving pressure from the NAB and their communities to halt broadcasts of Russian state-sponsored media like Russia Today and Sputnik:

NAB Calls On Broadcasters To Cease Russian Programming (Radio and Television Business Report)

It says it is a “fierce defender” of the First Amendment and “the critical importance of the ability to freely express views, both popular and unpopular.”

That said, the NAB explains that the First Amendment “does not prevent private actors from exercising sound, moral judgment.”

That’s why the chief advocacy group for broadcast radio and TV wants any state-sponsored programming with ties to Moscow pulled from U.S. airwaves now.

What will operators in Kansas City and Washington, D.C., do? RBR+TVBR heard from one of them, and he’s livid with the NAB. Another has placed the association among those responsible for “Cancel Culture” in the U.S.

In response to the invasion of Ukraine by Russia, NAB President/CEO Curtis LeGeyt seemingly took aim at Sputnik, the English-language service of the Voice of Russia.

Sputnik has already noticed, and reacted. On Tuesday, it noted that “Western governments” and internet giants including Google, Microsoft, Facebook and Twitter “have moved to heavily censor Russian foreign-language media outlets over the conflict in Ukraine, blocking websites, shutting down social media pages, and taking radio and television broadcasts off air.”

Calling the “censorship” unacceptable, Russian Foreign Ministry spokesman Oleg Gavrilov said in a meeting of the Russian Federation Council that, “separately, attention should be paid to the absolutely unacceptable behaviour of foreign, especially American, IT giants such as Google and Meta. Hostile propaganda activities are openly conducted on their social platforms, while Russian sources of information are blocked, and massive restrictions on access to domestic media are put in place.”

[…]“[G]iven the unprovoked aggression exhibited by Russia against the free and sovereign people of Ukraine, NAB calls on broadcasters to cease carrying any state-sponsored programming with ties to the Russian government or its agents,” LeGeyt said. “While we know that airings of such programs are extremely limited, we believe that our nation must stand fully united against misinformation and for freedom and democracy across the globe.”

Programs aren’t extremely limited to those in the Nation’s Capital, where Radio Sputnik airs on W288BS, at 105.5 MHz, and originating station WZHF-AM 1390, a directional two-pattern Class B facility first known as Top 40 WEAM. Both WZHF and the FM translator reaches much of greater Washington. [Continue reading…]

Why are Kansas City’s airwaves filled with pro-Putin ‘Radio Sputnik’ propaganda? (Kansas City Star Editorial Board)

“You’re listening to Radio Sputnik,’‘ the polished, made-for-radio voice says, accompanied by triumphant Russian-themed music. “Telling the untold.”

“Live from the divided states of America,” announces the host of “Fault Lines Radio” show. Produced in Washington, D.C., the program airs locally on AM radio station KCXL. Yes, we’re talking about a radio station spouting Russian propaganda from the heartland — just outside Kansas City. And why, you might ask, are Russian talking points airing on area radio stations?

Money talks. Or maybe we should say rubles.

Radio Sputnik, a media service funded by the Kremlin, airs daily on three stations in Kansas City. Alpine Broadcasting Corp. owner Peter Schartel is paid by Russian interests to broadcast pro-Vladimir Putin programming on them all.

And this week, with Russian tanks, artillery and troops continuing the tragic and reckless invasion of neighboring Ukraine, the Russian apologists spun hard. Schartel remained defiant even after multiple reports Thursday that the American branch of RT, the Russian-funded media network, was shutting down and laying off its staff. He said his contract was with an American company that works with the Russian authorities behind Sputnik. That company “has not notified us of any interruption,” he said.

For now, at least, the show goes on, and we sampled its absurd pro-Russian arguments so you wouldn’t have to.

Guests on the “Fault Lines Radio” show this week, encouraged by hosts Jamarl Thomas and Faran Fronczak, would have you believe Putin was an unwilling participant in this conflict. The Western media, one guest said, is complicit in spreading Ukrainian government war propaganda, and added that the besieged Ukrainian government is winning the information war on social media.

“If you were reading that, you might think there has been a billion Russian troops killed and that Ukrainian freedom fighters are storming Moscow,” said Mark Sleboda, Putin’s Moscow-based mouthpiece and frequent contributor to pro-Russian media companies.

Thomas predictably agreed, and the Putin praise continued.

KCXL has no ties to Russia and is against the country’s conflict with Ukraine, Schartel told us Wednesday. But he needs the money, and he’d lose his business if he pulled the plug on Radio Sputnik. So, that’s how you end up with a radio show here in the land of barbecue and jazz playing Cold War oldies and coddling a powerful, seemingly deranged dictator.

Putin ordered the invasion of neighboring Ukraine. The unprovoked and inhumane attack has caused thousands of deaths of both civilians and soldiers in Ukraine. Parts of the country are being reduced to rubble.

Outside of Moscow, the Russian invasion has been almost universally condemned. Except for right here in the Kansas City area, where listeners of KCXL were bombarded with pro-Putin talk. [Read the full article here…]

National Association of Broadcasters call to stop airing Russian radio, pressures Liberty radio station (KMBC)

LIBERTY, Mo. —Down a rural road just a mile away from Liberty’s city square, a radio station inside small brick building displays an American flag in the front window.

For six hours every weekday, 1140AM KCXL broadcasts radio programming paid for by the Russian government, called Radio Sputnik.

The National Association of Broadcasters earlier this week called for U.S. broadcasters to cease Russian-sponsored programming considering the war in Ukraine.

[…]Alpine Broadcasting Programming and sales manager Jonne Santoli-Schartel told KMBC on Thursday she and her husband, Peter Schartel, have no plans to pull Radio Sputnik from the station’s airwaves.

“If we can’t express our viewpoints anymore, and we have cancel culture, and people deleting and people putting pressure on other people to not hear certain programming, then we’re in trouble and freedom no longer exists,” Santoli-Schartel said.

Those living nearby disagreed.

“If the money means more than your morals, then you’ve got a problem,” said Debbie Bowman, who has family members from Ukraine.

Last year, government documents showed Alpine Broadcasting made at least $60,000 from RM Broadcasting, led by Florida businessman Arnold Ferolito. RM Broadcasting acts as a go between for two U.S. radio stations including KCXL, and Rossiya Segodnya, a media organization sponsored by the Russian government.

A judge in 2019 ordered RM Broadcasting to register as a foreign agent under the U.S. Foreign Registration Act.

That act makes sure people engaged in domestic political or advocacy work on behalf of foreign interests disclose financial information along with relationships.

[…]Santoli-Shartel also said she does not agree with the Russian invasion of Ukraine, however, she has no plans to stop broadcasting.

“My heart is breaking for these moms and these dads on both sides,” she said. “I think if I was in Russia, I would want to get out of Russia because I think they’re in danger also. But the people of Ukraine, I think it is so horrible.”

Turkey demands Deutsche Welle, VOA and Euronews apply for a licence (Broadband TV News)

Turkish media regulator RTÜK has given three international broadcasters 72 hours to apply for a licence or have their online content blocked.

Voice of America (VOA), Deutsche Welle (DW) and Euronews are including video on their websites and are seen as among the few independent news sources still available in Turkey.

RTÜK published a statement on its website Monday, signalling the start of the 72 hour period.

If the procedure for applying for a licence is underway, a broadcaster can continue on-air for another three months, providing the anticipated licence fee is paid to the regulator in advance. [Continue reading…]

Finding MH370: New breakthrough could finally solve missing flight mystery (60 Minutes Australia via YouTube)

Is the biggest aviation mystery of all time, the disappearance of Malaysia Airlines flight MH370, about to be solved? Yes, if you believe the man you’re about to meet. Richard Godfrey is no crackpot; he’s a respected British aerospace engineer and physicist who says he’s found the doomed airliner. If he’s right, he’ll provide desperately needed answers for the families of the 239 passengers and crew who were aboard the Boeing triple-seven when it vanished eight years ago. But knowing where it is isn’t the end of the story – Richard also has to convince authorities to resume the search that’s already cost hundreds of millions of dollars.

Retired electrical engineer, 85, has £15,000 collection of 200 antique radios that he has been building up for 50 years – including one of the oldest sets in the UK (The Daily Mail)

A grandfather-of-five has revealed his impressive antique radio and test instrument collection worth up to £15,000.

Richard Allan, a retired electrical engineer, has spent the last fifty years collecting antique transistor, valve and crystal sets and has now shown off his impressive collection of more than 200 pieces.

The 85-year-old from Norfolk, first fell in love with radios because of his father, Alexander William, who built his own transmitter and spoke to people all over the world through the airwaves.

In fact, Richard’s first – and favourite radio within his collection – is the one his father, a HAM, or amateur radio lover, played non-stop during World War II after purchasing in 1938.

Another notable piece within his collection is an E52b German military radio, captured in a vehicle at Foxhill, Bath, which was where his father worked in the Admiralty. [Continue reading…]

Jock explores “The Essential Listening Post Part II – When the lights go out”

Many thanks to SWLing Post contributor, Jock Elliott, who shares the following guest post:

When the lights go out: The Essential Listening Post – Part II

By Jock Elliott, KB2GOM

What’s the most valuable commodity in an emergency? Information.

Without information, it is very difficult to make decisions of what actions you should – or shouldn’t – take. Fortunately, as swling.com readers know, radio can come to your rescue.

As an example, I offer for your approval this minor incident that happened just a few mornings ago.

At 4:30 am, I awoke. That’s not particularly unusual; I get up early lots of mornings to run the Commuter Assistance Network on ham radio.

What made this morning unusual were the things I couldn’t see: the digital clock across the room, the tiny LED lamp that illuminates the way to the bathroom in the middle of the night. They were both dark. In fact, the only light that I could see was the LED from the uninterruptable power supply for the computer in the next room. It was pulsing, indicating the power from the mains was out.

With the help of a flashlight kept within easy reach of the bed, I made my way downstairs. A peek out the windows revealed the surrounding area was dark; no lights in local houses, no street lights. A house across the ravine behind my house had a single light, but it had the bright white look of an emergency lantern. So this outage was wider spread than just the lane where I live. But how widespread was it? In early February in upstate New York, it’s winter; temperature about 6 degrees Fahrenheit on this particular morning. The thermostat on the wall has already dropped below where the furnace should have kicked on. With no electricity; no furnace.

With no house power, I had no internet, so I couldn’t look things up to find out why there was no house power. Because we use Voice Over Internet Protocol (VOIP), with no internet, no house phone.

Now, I know what you’re thinking: “Well, dummy, fire up your smart phone, and in a few moments you’ll have your answers.”

To that I say: “Not so fast there, pardner.

I consulted with a ham radio friend who makes his living in the commercial radio business. He consults with many companies, including cell phone companies, so he knows what he is talking about.

It turns out there are three things that could render your smart phone useless.

The first is whether your local cell tower(s) have battery back-up. Most do, but how many hours the batteries will run the cell tower can vary widely from just a couple of hours to perhaps eight. Depending upon when the power went out, you may or may not be able to connect.

The second is that many cell phone towers themselves connect to the rest of the network through wire or fiber optic cable. If a vehicle has taken down a pole, or a falling tree has taken down a cable, the network may be disrupted.

Finally, if there is high demand for your local cell phone tower, you may not be able to make a connection. My commercial radio “guru” relates that he went to an event at a local community college. There is a cell tower right on the property, but he had great difficulty connecting simply because so many people were trying to use the tower.

During emergencies, cell phone networks frequently go into gridlock because of high demand, so it’s a good idea to have other means of gathering information. An interesting aside: some years ago, I heard a presentation from one of the hospital administrators who was in New Orleans during Hurricane Katrina. They were unable to make voice phone calls, but apparently they could sometimes send and receive text messages.

Getting back to my small lights-out incident, I was in the actual act of firing up a radio to check out what local broadcasters on the AM (medium wave) band had to say, when the lights came on, the furnace started, and internet and phone service were restored. My greatest inconvenience was having to reset a couple of digital clocks.

But it raised a serious question: what should be your essential listening post if the lights go out, the fertilizer hits the ventilation equipment?

First and foremost, a battery-powered radio capable of receiving your local broadcasters. You need to know – or find out – which ones have back-up power so they can keep transmitting. Knowing that will do two things for you: first, tuning in to a station with back-up power will hopefully get you the information you need, and second, if stations that don’t have back-up power are off the air, that will give you an indication of how widespread the power outage is.

Knowing the extent of the blackout can be important. A couple of decades ago, on an August afternoon, my better half and I took our young son to a local park where there was a water fountain that the kids could run through. When we got home later, the power was out. I saw the neighbor standing in her yard and asked if she had reported the outage. “No point,” she said. “Why?” I asked. “Because the lights are out from Canada to Virginia.” Oh.

In addition to knowing which stations are likely to be on the air, it’s also good to know which local stations have news staff that are likely to collect and broadcast information that is needed during an emergency.

Second, if you live in the United States or Canada, you need a weather radio. Every state in the Union has bad weather of one sort or another . . . and some of them can kill you. NOAA weather radio is an excellent source of information. It’s free, and it does a fine job of delivering weather-related info in a concise and useful format.

Third, it would be very useful to have a scanner or ham radio capable of receiving your local 2 meter repeaters. This could be an additional source of useful information in a crisis.

So, are there any radios that I would recommend for “The Essential Listening Post” when the lights go out?

Yes, there are.

The C.Crane CCRadio 2E

First on my list would be the C.Crane CCRadio 2E (or CCRadio3). It receives AM, FM, NOAA Weather Band with Weather Alert and the 2-Meter Ham Band. It will run on house power or, if the lights are out, over 200 hours on batteries. By all accounts, it offers excellent performance on AM and FM, and it is one of the most sensitive NOAA weather radio receivers I have tested. I bought one and can heartily recommend it.

CC Skywave SSB

The CCrane Skywave SSB receives AM, FM, NOAA Weather band plus Alert, Shortwave (1711-29.999MHz) with SSB, VHF Aviation Band. It doesn’t receive the 2 meter ham band, but it will receive hams on HF frequencies, which might come in handy in an emergency. It is not quite as sensitive as the CCrane 2E on NOAA weather frequencies, but, as I reported last year it was the most sensitive NOAA weather radio receiver I took to Sodus, NY. It is very small and portable and will run for over 50 hours on batteries. I bought one and can heartily recommend it.

The Eton FRX3+

The Eton FRX3+ is an interesting alternative for a “when the lights go out” radio. This battery-powered radio receives AM, FM, and NOAA weather radio with alert. It has a couple of LED lights for navigating in the dark and can be charged by a built-in solar panel, hand-crank, or USB cable, and can even be used to charge your cell phone. Eton Corp. sent me one of these, and I find that it offers worthy performance on AM and FM, and excellent sensitivity on NOAA weather radio. Recommended.

In the future, I hope to offer some additional useful information about NOAA weather radio as well as a comparison of different ways to receive NOAA weather radio, including dedicated weather radio, consumer radio, scanner, and ham handi-talkie.

Much thanks to the many contributors who shared the following items:


You’re listening to KUOW … like it or not: Mysterious glitch has Mazda drivers stuck on public radio (Geekwire)

Drivers of certain vehicles in Seattle and other parts of Western Washington are shouting at their car radios this week. Not because of any particular song or news item that’s being broadcast, but because an apparent technical glitch has caused the radios to be stuck on public radio station KUOW.

The impacted drivers appear to all be owners of Mazda vehicles from between 2014 and 2017. In some cases the in-car infotainment systems have stopped working altogether, derailing the ability to listen to the radio at all or use Bluetooth phone connections, GPS, the rear camera and more.

According to Mazda drivers who spoke with GeekWire, and others in a Reddit thread discussing the dilemma, everyone who has had an issue was listening to KUOW 94.9 in recent weeks when the car systems went haywire.

KUOW sounded unsure of a possible cause; at least one dealership service department blamed 5G; and Mazda told GeekWire in an official. [Continue reading…]

The real reason the 1930s were considered ‘the golden age of radio’ (The Grunge)

While it’s been widely contested who actually invented the first radio (both Italian physicist Gugliemo Marconi and Serbian-American inventor and engineer Nikola Tesla were fighting for the first patent, per PBS), it was Marconi who came out top in 1904, when the U.S. Patent Office officially dubbed him the inventor of the new breakthrough technology. According to APM Reports, in 1920, Americans had their first commercially licensed radio station in Pittsburgh, Pennsylvania: KDKA. That number quickly rose after KDKA broadcast the election that saw Warren G. Harding become the 29th president, and by 1924, 500 stations were available for listening.

By 1930, over “40% of American households owned a radio,” per APM Reports. This became known as “The Golden Age of Radio.” As revealed by PBS, in 1930, 12 million Americans owned radios — growing to a whopping 28 million by the end of the decade.

Access to the radio came at a turbulent time in history. As the Great Depression caused widespread suffering for millions of Americans (via History), the households that could afford a radio saw it as a welcome source of entertainment and news that made them feel connected to the rest of the country. These days, with over 15,445 radio stations available in the U.S., it’s clear the radio still remains relevant, but its impact on society truly began nine decades ago. Let’s take a look at the real reason the 1930s were considered “The Golden Age of Radio.” [Continue reading…]

Russia initiates cross-border radio broadcast in North’s languages (Russian News Agency – TASS)

ST. PETERSBURG, February 7. /TASS/. The International Consortium for the Preservation of Arctic Cultural Heritage, based at the Russian State Hydrometeorology University (RSHU), initiated a cross-border radio broadcast in languages of the North’s indigenous peoples, the university’s representative in Moscow Andrei Bryksenkov told TASS.

An application for the broadcast has been filed with the Arctic Council. “The application must be filed from two countries, and we plan to go along with Norway – with the Sami Radio, which is a part of Norway’s big television and radio concern. <…> The idea has been supported at all levels. As for the cross-border broadcast, we, probably, will begin from the shortwave broadcast, as it covers bigger territories and is less costly,” he said.

At the initial stage, the pilot broadcast will be organized on the territories of Finland, Norway and Russia. The project’s initiators are ready to cooperate with other countries. “One transmitter in Krasnoyarsk may cover 80% of the Russian North. Norway has such a transmitter, which covers the Scandinavian territory. Another two transmitters are on Alaska,” he continued. Later on, the broadcast will be also on middle and long waves, thus one frequency will carry 3-4 channels, he added. One of them will be in Russian and English, and the rest – in languages of the indigenous peoples.

The audience will learn about traditions, skills of the peoples living in the North. The content will fully focus on culture. The countries, participating in the project, will open newsrooms. “We hope the general center, which will coordinate the project, will be at the Arctic Council,” he said.

The International Consortium for the Preservation of Arctic Cultural Heritage includes St. Petersburg’s committee on the Arctic, the Arctic museum and exhibition center in St. Petersburg, the Association of indigenous low-numbered peoples of the North, Siberia and Far East, and others.

FCC Is ‘Cleaning Up’ Of More Radio Rules. Here Is What Will (And Will Not) Change. (Inside Radio)

The modernization of radio’s regulatory rulebook that began under the prior administration continues at the Federal Communications Commission. It is slated to approve a half dozen changes at the Commission’s February meeting, in what Chair Jessica Rosenworcel says is a “cleaning up” of the broadcast radio rules.

“The Commission’s current rules for full-power and translator radio stations contain a number of provisions that are redundant, outdated, or in conflict with other rules,” said Rosenworcel. She said the proposal would “update and clean up” those provisions “in order to reduce any potential confusion, alleviate unnecessary burdens, and make sure our rules reflect the latest technical requirements.”

The proposed order (MB Docket No. 21-263) would update six rules, while scrap plans to change another. They include –

Eliminate Transmitter Power Limit Rule For AMs.

The draft order says the FCC has tentatively concluded the rule is “outdated and unnecessary” given its current reliance on actual operating antenna input power as the most accurate and effective means of ensuring that AM stations adhere to their authorized power limits. The FCC also agreed with comments filed by the National Association of Broadcasters that said the elimination of the technical restriction will allow AMs of any class to use transmitters of any rated power. That, it says, will benefit all AMs by broadening the market of transmitters, enhancing the secondary market for AM transmitters, and reducing the number of transmitters that need to be disposed of.

Clarify AM Fill-in Area Definition

The FCC is poised to amend the definition of an “AM fill-in area” used when an FM translator simulcasts an AM station. [Continue reading…]

Geomagnetic storm and recently deployed Starlink satellites (SpaceX Blog)

On Thursday, February 3 at 1:13 p.m. EST, Falcon 9 launched 49 Starlink satellites to low Earth orbit from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. Falcon 9’s second stage deployed the satellites into their intended orbit, with a perigee of approximately 210 kilometers above Earth, and each satellite achieved controlled flight.

SpaceX deploys its satellites into these lower orbits so that in the very rare case any satellite does not pass initial system checkouts it will quickly be deorbited by atmospheric drag. While the low deployment altitude requires more capable satellites at a considerable cost to us, it’s the right thing to do to maintain a sustainable space environment.

Unfortunately, the satellites deployed on Thursday were significantly impacted by a geomagnetic storm on Friday. These storms cause the atmosphere to warm and atmospheric density at our low deployment altitudes to increase. In fact, onboard GPS suggests the escalation speed and severity of the storm caused atmospheric drag to increase up to 50 percent higher than during previous launches. The Starlink team commanded the satellites into a safe-mode where they would fly edge-on (like a sheet of paper) to minimize drag—to effectively “take cover from the storm”—and continued to work closely with the Space Force’s 18th Space Control Squadron and LeoLabs to provide updates on the satellites based on ground radars.

Preliminary analysis show the increased drag at the low altitudes prevented the satellites from leaving safe-mode to begin orbit raising maneuvers, and up to 40 of the satellites will reenter or already have reentered the Earth’s atmosphere. The deorbiting satellites pose zero collision risk with other satellites and by design demise upon atmospheric reentry—meaning no orbital debris is created and no satellite parts hit the ground. This unique situation demonstrates the great lengths the Starlink team has gone to ensure the system is on the leading edge of on-orbit debris mitigation. [Read at SpaceX…]
